Airbnb website inaccessible in Europe. They forgot to renew their certificate

Sweden the site is down, but it can still be accessed in FF which is odd that they are the only browser. Tried on Chrome, Opera, IE 11, and Edge. To be clear this is using https://airbnb.com.

That is signed by DigiCert vs. airbnb.de is signed by GlobalSign. Something fishy here.

Works fine in France right now.

Germany as well. Even in Firefox which loves to nag about invalid certs.

Just tried replicating it in Firefox, and it seems that Chrome and Firefox accept different certificates for airbnb.com. Tried on three different platforms (Windows, Ubuntu and Android), same thing: Firefox uses a valid GlobalSign certificate, while Chrome uses an invalid DigiCert certificate.

Never seen the same website using different certs for two different browsers before.
